CLEVIS.

Application filed May 20, 1916.

To all whom it may concern Be it known that I, CLARENCE KISSIN- can, a citizen of the United States, residing at Pierson, in the county of Voodbury and State of Iowa, have invented certain new and useful Improvements in Clevises, of which the following is a. specification.

This invention relates to clevises, and has for its object the provision of a. clevis and clevis pin which will mutually cooperate to prevent loss of the pin while the clevis is 111 use.

The invention is illustrated in the accompanying drawings and consists in certain novel features which will be particularly pointed out in the claim following the description.

In the drawing: Figure l is an elevation partly in section of a clevis and pin embodying my present improvements; Fig. 2 is a perspective view of the pin.

The clevis body consists of parallel arms 1 and a semi-circular connecting shoulder 2 joining the arms at one end. In the other ends of the arms I form openings 3 which receive the pin 4 and the wall of one of these openings is annularly enlarged at its outer end as shown at 5. The pin 4 has its ends offset sharply from its intermediate portion thereby forming shoulders 6, and upon one end of the pin is a head 7 which is adapted to impinge against the adjacent side of the clevis body and thereby prevent the pin passing entirely through the arms of the clevis. At the end of the pin remote from the head 7 is a lug 8 which is disposed upon the circumferential surface of the pin and is adapted to seat in the annular recess 5, as clearly shown in Fig. 1.

In use the clevis is attached to the implement to be drawn in the usual manner and the pin 4 is inserted through the openings 3 to be engaged by the draft device. The openings 3 should be sufficiently large to permit the pin, with the offset portions thereof, to pass entirely therethrough. When draft is applied to the pin, it will be Specification of Letters Patent.

drawn forward in the openings 3 so that it will bear against the forward walls of the openings and the offsets or shoulders 6 will engage against the inner faces of the clevis arms so that movement of the pin along its axis will be prevented. This result is enhanced by the engagement of the lug 8 in the seat 5 so that movement of the pin laterally with respect to the clevis will be posi tively prevented but the said lug is not indispensable and may be omitted, the annular recess then being unnecessary and the cost of manufacture consequently reduced. When the draft upon the pin ceases and it is desired to uncouple the draft devices, the pin may be easily moved so that its ends will bear against the rear walls of the openings 3, after which the pin may be moved endwise so as to be withdrawn from the clevis arms.

The device is exceedingly simple in its construction and may be easily manipulated. It may be produced at a very slight cost and will be found highly efficient in use.

Having thus described the invention, what is claimed as new is:

The combination with a clevis including spaced arms having lateral openings at their ends and provided with a recess in the wall of one of said openings, of a clevis pin adapted to be inserted through said openings and having its entire intermediate portion offset bodily from the ends thereof to provide annular shoulders adapted to engage between the opposed inner faces of the arms of the clevis, one end of the pin being provided with an enlarged head adapted to bear against the outer surface of one of the arms and the other end of the pin being provided with a laterally extending lug spaced from the adjacent annular shoulder and adapted to seat within the recess, the lower face of the pin and lug being disposed in the same plane and flush with the outer surface of the other arm of the clevis.

In testimony whereof I aflix my signature.
